ABSTRACT:
Oxygen is extracted from a fluid mixture feedstock by circulating a carrier fluid from an oxygen loading station to an electrochemical cell. The carrier fluid includes a carrier compound capable of reversibly binding oxygen, with oxygen binding dependent on the oxidation state of the compound. Oxygen bound to the carrier compound in a first oxidation state is released as the oxidation state is altered at the first electrode of the electrochemical cell. The carrier compound is then returned to the first oxidation state at the second electrode at the electrochemical cell. The loading station typically comprises an oxygen-permeable membrane which prevents bulk mixing of the fluid mixture and the carrier fluid. By providing an electrocatalyst capable of rapid electron transfer and having an electropotential less than that of the carrier compound, without binding or otherwise interfering with the carrier compound, low energy electron transfer between the carrier compounds and the electrodes of the electrochemical cell is achieved.
